on the action's default, reverting it back to previous behavior. Conversion
is only done on string defaults.
Add a test for this and another test that ensures such type conversions are
only called once.
This fixes a regression introduced by the fix for issue #13922. Although args
is not documented as being allowed to be a tuple, previously this worked and
so naturally there are programs in the field that depend on it.
Patch by Zbyszek Jędrzejewski-Szmek.
Before, the type function was called twice in the case where the default
was specified and the argument was given as well. This was especially
problematic for the FileType type, as a default file would always be
opened, even if a file argument was specified on the command line.
Patch by Arnaud Fontaine, with additional test by Mike Meyer.

Fix incorrect use of gettext in argparse (#10497).
Steven, the maintainer of argparse, agreed to have this committed
without tests for now, since the fix is obvious. See the bug log.

#9444: use first of prefix_chars for help opt instead of raising error
An argparse option parser created with a prefix_chars that did not
include a '-' would happily add -h and --help options, and then throw
an error when it tried to format the help because the - was an invalid
prefix character. This patch makes it use the first character of
prefix_chars as the character for the help options if and only if '-'
is not one of the valid prefix_chars.
Fix by Theodore Turocy, unit tests by Catherine Devlin.
........
Docs still need some updating to make getopt and optparse match the wording promised in the PEP.
There are also probably a number of :class:ArgumentParser etc. links that could be added to the argparse documentation.
